When an SVC node goes down as part of a node reboot, its WWPNs are moved to the remaining node. When the node is back online, its WWPNs are moved back. The result is that the WWPN moves from one NPort_ID to another, then back again. The ibmvfc driver was forcing the old port to be removed, but not sending an implicit logout. When the WWPN showed up at the new location, the PLOGI failed as there was already a login established for the old scsi id. The patch below fixes this by ensuring we always send an implicit logout for any scsi id associated with an rport prior to calling fc_remote_port_delete.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
